TDataReadMapDataFailed: Unknown key type in encrypted map: 25 [ Called by BaseObject.MapData.read() ]

[VectorASD]

Describe the bug
Parsing the innards of TDesktop revealed that there is one single account, but its isLoaded = false. Digging deeper, it turned out that the error TDataReadMapDataFailed: Unknown key type in encrypted map: 25 [ Called by BaseObject.MapData.read() ] inside the readMapWith function of the accaunt class.

Expected behavior
TDesktop ended without exceptions.

Screenshots

Additional context
Telegram Desktop is working, so the 25-type key is not a lie.
